This works, but since it's not clear to me how much the popup and the storyboard know about each other, I was wondering if there was any situation in which the popup might display before the story board starts. For example, does it depend on a UI cycle
time with the popup waiting to open at the start of the next cycle, and if the storyboard starts in the same cycle the fade in will happen, otherwise not?

Another possibility that occurred to me was that since I'm animating the opacity to do the fade in, I could set the popup's opacity to 0 before calling Popup::Open(). Then, even if the popup is open before the animation starts, it shouldn't matter.
